Floor plan tube house L-shape triangular plot including oak tree

Then sketch in how the neighboring house is situated.

And garage in the basement=cellar? Is there also a slope there? Then roughly mark elevation points in the triangle.

And don’t make me pull everything out of your nose one by one

The neighboring buildings are shown in the picture, 222 and 224. The neighbor has granted himself a spacious yard.

Yes, we want the garage underground so that the basement apartment can have windows on the street side. This is achieved by allowing light to enter via the driveway to the garage. Also, a front door to the apartment immediately in front of the garage door.

There is a slight slope. Elevation points: 252.56 on the left, 252.31 on top, and 251.35 on the bottom.

I have no intention of withholding any information from you. But I’m happy to provide everything upon request.

I think we will have to plan for an L-shaped building. Flat roof, many windows, especially downstairs, because the orientation and the tree cost a lot of light. We want a simple building, nothing extravagant.

I have never built before and am thus a rookie. I hope for some newbie protection.

Why a granny flat?

I would have planned a rectangle, as far east as possible.
With an L you take away the southern sun.

Difficult small plot, big house, triangular shape and huge tree

2 floors and a basement. In the basement we are planning a granny flat. Living area 200 sqm, rather a bit more.
Garage in the basement on the right towards the neighbor.

This is a simple house without extras:



But that’s not what you mean, right?

The question of placement, in my opinion, does not arise. I haven't read anything about permitted edge construction or the like here. That means 3m distance to all boundaries. With a bit of luck, it might be only 2m to the public paths or so. But I wouldn't assume that for now, and whether that would look good is also questionable.

A 10x10 house doesn't even fit into the building plot. Or did I fundamentally misunderstand something? Here, you will probably even have to build diagonally to get enough square meters. What are the floor area ratio and plot ratio? I think the tree is your smallest problem.

This might get interesting. 200m²? Only if you were allowed to build three floors, perhaps.

But you don't mean that, do you?

No. Right

I think the tree is your smallest problem.

I believe that is the biggest problem. A 7m oak certainly falls under the tree protection ordinance of the municipality, and generally the entire crown drip line area is off-limits for construction or sealing. So first clarify with the municipality which area is actually available for construction, then you can deal with the details.
